Tooltips

Overview

A tooltip is a text box displayed when a point on a chart is hovered over, which allows you to show the detailed information about an event marker. You can either adjust the built-in AnyChart tooltips or create custom HTML tooltips.

Built-In Tooltips

The built-in tooltips of event markers work the same way as any other tooltips - see the Tooltip article. There is a number of visual and other settings available: for example, you can edit the text by using font settings and text formatters, change the style of background, adjust the position of a tooltip, and so on.

When you create data for event markers, you can add an optional data field - description. By default, it is shown in tooltips, and if there is no description, the symbol of a group is shown instead.

The built-in tooltips are adjusted with the help of either tokens or formatting functions.
